JOHN S. HENRY AND ABRAHAM H. REIST, OF MANHEIM, PENNSYLVANN Lctte rs Patent N0. 68,195, dated August 27, 1867 IMPROVEMENT IN HORSE HAY-PORKS.

T0 ALL WHOM IT MAY CONGERN:

Be it know n that we, JOHN S. HENRY und ABRAHAM H. REIST, of Manheim, in the countyof Lanea'ster, and State of Pennsylvania, have inventecl a. new and useful Improvement on HorseForks for Elevating Hay; and ive (10 hereby declare Chat the following is a full, clear, and exact description of the construction und operatior'1 of the same, reference being had to the accompimying drawings, making a pa/rt of this specification, in ivh"ich Fi'gure 1 is a perspective (lxawing of the elei*ator, with the polnt ab right angles to the double shaft, with my impxove me'nt in place.

Figure 2, the same when the point is extended in a. lge with t he shaft.

Figure 3 illustrates the change of position frm fig. 1 to fig. 2 by the dotted lines.

The natura of 0a1r invehtion cnsistg in the arrangement of the parts to give efliciency t0 machinesof this dass for elevating hay, so to locate the pivotcd point and operate it by a lock o1 springcatch in a mahner to prevent it from, releasing its load until the lever is actually unlocked by the action of tlie cord in the hands of the Operator. This, I am aware, is performecl on somc 0f the numerus inventions alreacly patented, difl'ering,

however, in other respects substantially in theirarrangemnt.

T0 enable others skilled in.the art; to make and use 0111 inventi on we will prceed to describeits' construction und operation, clearly shown by the clrawings.

We em ploy a p air of parallel bars, A A, of staut strap iron ot snfiicient length and strength. The upper end is continued into a; loop, b, for the lxoisting rope, or. a. piece expressly mnde and boltecl 011 the ends of the bars AA, where they'ale joined by intefposing a oross-plug or piece, so that the bars are separate l ab an equal distance a}arflheir cntire leng'th. spiralspring surrounds a roll terminated with an eye, H, projecting at one end, and a liatch, K, at the lower end from spring-bei B. This catch K loeks into a notch, g, on the lever C, whicli li1tter has an cye at one en l for a rope connection, and the ol:her end is connectecl by a pivotto a bar D, operating bctiveen the bars A A. Said leveris helcl by a pivot between the bars a't T. The jointed bar D o1 -lc vcr is connected by a pivot at its lower e'nd, ab 0Z with the terminal point E held by its irlfier end ab a, between the parallel bars upon whicl1 it moves as a fulorum. The osition of this point E an'd lever-bar D is shown when the 1m:er-bar G is lacked by the spring-holt; K H, by fig. 1. When in this position it is being elevated with a. load of hay hold by the side tines F and point E, to cause it to discharge it s load ii: is only necessary to draw upon the corcl R passing (wer a pulley, P, to the eyo of the spring-holt H, which draws the bolt K out of the notcl1 g, so tha-t the \veight rosting on the point E will now cause it to straighten out, aml thereby discharge tl1e hay when tl1e arts zl'ssume the position shown by fig. 2, ready.for plunging into the l1ay again for a fresh load. By pushing the arm G up against tl1e bars A, the spring-bolt mechanical'ly locke the part as the lower poinf is again thrown auf; at right anglos to the bars. The operation is shbwn by fig. 3, already referred to.

lrVe :ue aWare that the side tines F an l action of tlie point E are not new, 21.I1l1 intleed all, separately cousidered, a1e again and again used in the various combinationa in a manner to produce similax results, but difier ing substantially in their arrangement. The points in use do not stand square withtlxe end's of parallel bars, atul move l by a-a inernal ooinbinecl lever with another lever having a lock-notcl1' for the action of a spring-holt, thus constituting a val uable im'pfovement by this arrangement, which results in making it efiicient and relia-ble for the purpse intcndecl, an l obviating the defects and objections to elevators of this class heretofore introcluced. Wo du not claim the pivoted point, side profigs, spring bolt, catch, &c. separately considered, for such arc i n use undcr vzirious combinations, the special arrangements of which are claimed in divers 'manners, euch (liflering, ns ours difl'ers from all of them.

What wo claim as ou1 invention', und desire to secure by Letters Patent, is-

'lhc arrangement of the notched lever G,"in combination with the spring-holt K Hfor ope'rabing the point E by a eonneoting-lever, D, btwecn the parallel bais A A, all combined a.nd operating in the'manner and for the purpose spceified.
